safety and tolerability study for the pneumococcal conjugate vaccine v114 versus prevnar™ (v114-001)

Conditions: Pneumococcal Infections

Summary: this study is being conducted to evaluate the safety, tolerability, and immunogenicity of 15-valent pneumococcal conjugate vaccine (v114) compared to prevnar™ in healthy adults and toddlers.

the study was extended to obtain additional sera from adult participants to support further development, validation, and performance of anti-pneumococcal antibody assays.

(exception: inactivated influenza vaccine may be administered during the study, but must be given at least 7 days prior to receipt of the study vaccine or at least 15 days after receipt of the study vaccine.) * participant has received a licensed live virus vaccine within 30 days prior of receipt of study vaccine or is scheduled to receive vaccination with a licensed live virus vaccine within 30 days of receipt of study vaccine. * participant has received diphtheria toxoid within 6 months prior to receipt of study vaccine. * prior receipt of a blood transfusion or blood products including immune globulin administered within the 6 months before receipt of study vaccine. * investigational drugs or vaccines received within the 2 months before receipt of study vaccine. * participation in another clinical study within 42 days before the beginning or anytime during the duration of the current clinical study. * recent hospitalization for acute illness within the 3 months before receipt of study vaccine. * history of invasive pneumococcal disease (positive blood culture, positive cerebrospinal fluid culture, or other sterile site) or known history of other culture positive pneumococcal disease. * history of febrile illness (≥100.40 f \[≥38.00 c\] oral or equivalent) occurring within 72 hours before receipt of study vaccine. * participant is pregnant or breastfeeding or expecting to conceive within the projected duration of the study. female participants of reproductive potential must have been using 2 acceptable methods of birth control for 2 weeks prior to enrollment, and agree to use 2 acceptable methods of birth control for 1 month after vaccination. (acceptable methods of birth control include use of hormonal contraceptives, intrauterine device (iud), diaphragm with spermicide, contraceptive sponge, tubal ligation, condoms, or abstinence). * any participant who cannot be adequately followed for safety according to the protocol plan. * participant is unlikely to adhere to study procedures, keep appointments, or is planning to relocate during the study. * any other reason that in the opinion of the investigator may interfere with the evaluation required by the study. toddler stage: * have received less than the full 3-dose infant series of prevnar™ or 3rd dose less than 2 months before study vaccine. * known hypersensitivity to any component of the pneumococcal conjugate vaccine. * known or suspected impairment of immunological function. * participant has a history of congenital or acquired immunodeficiency (e.g., splenomegaly). * participant or his/her mother has documented hiv infection. * functional or anatomic asplenia. * history of autoimmune disease including multiple sclerosis (ms), systemic lupus, polymyositis, inclusion body myositis, dermatomyositis, hashimoto's thyroiditis, sjogren's syndrome, rheumatoid arthritis, other autoimmune disorders. * known neurologic or cognitive behavioral disorders including multiple sclerosis (ms), ms-like disease, encephalitis/myelitis, acute disseminating encephalomyelitis, pervasive developmental disorder, and related disorders. * receipt of intramuscular, oral, or intravenous corticosteroid treatment within the 2 weeks prior to vaccination. (note: toddlers on topical and inhaled/nebulized steroids may participate in the study.) use of systemic steroids are only permitted when the participant is receiving less than 2 mg/kg per day of prednisone (or its equivalent), or less than 20 mg/d if they weigh more than 10 kg and are not otherwise immunocompromised. * participant has received other licensed non-live vaccines administered within the 14 days before receipt of study vaccine. * participant has received a licensed live virus vaccine within 30 days prior of receipt of study vaccine (exception: influenza virus vaccine given according to recommended guidelines within 7 days of receiving study vaccine). * prior receipt of a blood transfusion or blood products, including immunoglobulins. * investigational drugs or vaccines received within the 2 months before receipt of study vaccine. * participation in another clinical study within 42 days before the beginning or anytime during the duration of the current clinical study. * history of invasive pneumococcal disease (positive blood culture, positive cerebrospinal fluid culture, or other sterile site) or known history of other culture positive pneumococcal disease. * a recent (\<72 hours) febrile illness (rectal temperature ≥38.1°c \[≥100.5°f\]) occurring within 48 hours before receipt of study vaccine. * history of failure to thrive. * participant has a coagulation disorder contraindicating im vaccination. * participant and his/her mother is documented hepatitis b surface antigen-positive. * any toddler who cannot be adequately followed for safety according to the protocol plan. * participant's parent/legal guardian is unlikely to adhere to study procedures, keep appointments, or is planning to relocate during the study. * any other reason that in the opinion of the investigator may interfere with the evaluation required by the study.
